All of the above

Dipole-dipole, hydrogen bonding, van der Waals interaction

Charge-dipole, hydrogen bonding and van der Waals Interaction

None of the above

Hydrophobic effect, hydrogen bonding and dipole-dipole interaction

All of the above

Explanation / Answer

Molecules CH3CH2CH2CH2OH and CH3CH2CH2CH2NH2, in the absence of any other molecules, can interact with each other via non-covalent interactions that include Dipole-dipole, hydrogen bonding, van der Waals interaction. Both alcohol and amine are polar molecules. Hence, they constitute dipoles. This results in dipole-dipole interactions. In these compounds, H atom is attached to more electronegative N and O atoms. Hence, hydrogen bonding is possible. Due to presence of hydrocarbon chain, van der Waals interaction is possible.
